William Mason (22 October 1757 – 7 February 1818)[1][2] was a militiaman in the American Revolutionary War and a prominent Virginia planter. Mason was the son of George Mason, an American patriot, statesman, and delegate from Virginia to the U.S. Constitutional Convention.

Early life and education[]

Mason was born on 22 October 1757.[1][2] He was the fourth child and third eldest son of George Mason and his wife Ann Eilbeck.[1][2] Like his brothers, Mason was educated by tutors at Gunston Hall.[1]

American Revolutionary War[]

During the American Revolutionary War, Mason served in the Fairfax Militia fighting under Henry Lee III in South Carolina.[1][3] He was commissioned a Captain.[1] In 1780, Mason's father declined an offer by Lee to continue his military service because his father felt Mason's "lot must be that of a farmer and gentleman."[1] Mason was presented with a sword by General George Washington, which was said to have been given to him by Charles III of Spain.[3] Mason returned to private life between December 1780 and June 1781.[1]


In 1780, Mason inherited the Eilbeck family estates, Araby and Mattawoman, in Charles County, Maryland, from his maternal grandmother, Sarah Eilbeck.[1][4] The Mason family occupied Araby until 1849.[4] In 1849, 402 acres (1.63 km2) including the mansion were sold by Mason's daughter Mary Elizabeth Mason to William Thompson.[4]

Mason also received all his father's properties in Charles County.[1] These properties were located along Chicamuxen and Mattawoman Creeks.[5]

Marriage and children[]

Mason married Ann Stuart, daughter of William and Sarah Stuart, on 11 July 1793 at St. Paul's Episcopal Church in King George, Virginia.[1][2] The couple had five children:[1][2]

  • William Stuart Mason (1795–7 March 1857)[1][2]
  • George Mason of Hollin Hall (11 November 1797–25 March 1870)[1][2]
  • Ann Sarah Stuart Mason Heileman (1803–9 November 1852)[1][2]
